Detailed Description

The ResourceManager class contains methods that simplify the use of Resources.

Member Function Documentation

◆ comparePermissionLevels()

static comparePermissionLevels	(	$level = `'user'`,
		$other_level = `'user'`
	)

static

Compares two resource permission levels and returns an integer telling if the first level is less than (-1), equal (0) or greater than (1) the second level.

Parameters

string	$level	The first permission level.
string	$other_level	The second permission level.

Exceptions

InvalidArgumentException if $level or $other_level are either not set or if they contain invalid permission level strings.

Returns: integer -1 if $level is less than $other_level, 0 if both are equal, 1 if $level is greater than $other_level.

	)

static

Creates a copy of a resource and stores the copy in the database.

Parameters

Resource	$resource	The resource which shall be copied.
